This skill provides guidance for defining, using, and improving Claude subagents—the specialized agents that handle specific domains like , , , and .

When delegating to subagents, use the mandatory 7-section structure:

1. TASK: Atomic, specific goal (one action per delegation)
2. EXPECTED OUTCOME: Concrete deliverables with success criteria
3. REQUIRED SKILLS: Which skill to invoke
4. REQUIRED TOOLS: Explicit tool whitelist (prevents tool sprawl)
5. MUST DO: Exhaustive requirements - leave NOTHING implicit
6. MUST NOT DO: Forbidden actions - anticipate and block rogue behavior
7. CONTEXT: File paths, existing patterns, constraints

See subagent-types.md for detailed guidance on which subagent to use:

Only create subagents when: The task domain has distinct tooling, expertise, or patterns that benefit from specialization.
